I’ve been looking for new AA/AAA chargers for travel (I use AA batteries in my scubadiving flashlight), that would be as minimal as possible, AND will have USBC, and ideally one that can take more power to charge at 1A vs 0.5A even in an 8 battery configuration. Took me some time to look it up - ut eventually found the ISDT Air series.
This charger is as small as I’ve ever seen - it’s literally the size of a case for 4/8 batteries, only it can also charge. it has led indicators for status, but what’s even more cool is that it has BT so you can connect an app from your phone to get full data, which is very cool.
Also - thanks to BT, it can do firmware updates. as I got it in insisted on doing FW update on both. Maybe this is to fix some problems a few people reported on in some of the reviews Ive seen (wrong decisions on termination of charging). For the time being mine charges well, and the app is a nice touch for such a small travel charger.
